| From radar beginning applied big value at the military realm, various aim at radar signals of intercepted and jammed also immediately get a large-scale application with interference means. The technique of low probability of intercept is efficiency to resist intercepter and jammer. The low probability of intercept radar will has more survive probability then others in the complex electronic battle field.This article interducted the techniques suitable of airborn fire control radar. The article shown that the two main keys of LPI are power management and make the intercept not matched the radar signals. This article analysed various types of intercept receivers. Aim at the mainstream of intercept receivers-the instantaneous frequedcy measurement receivers and channelized intercept receivers,the article shown the emluatoion results of various LPI waveforms passed the intercept receivers. and interducted some types of stealth waveform.This article also gived a method to decrease the large date number of LPI date process;and gived a kind of waveform of double frequency diversity with large bandwidth linear FM , and the system composing. |
